Overview - Vascular dementia

Vascular dementia can start suddenly or begin slowly over time. Symptoms include: slowness of thought difficulty with planning and understanding problems with concentration changes to your mood, personality or behaviour feeling disoriented and confused difficulty walking and keeping balance symptoms of Alzheimer's disease , such as problems with memory and language (many people with vascular dementia also have Alzheimer's disease) These problems can make daily activities increasingly difficult and someone with the condition may eventually be unable to look after themselves.

See a GP if you think you have early symptoms of dementia, especially if you're over 65 years of age. If it's found at an early stage, treatment may be able to stop vascular dementia getting worse, or at least slow it down. If you're worried about someone else, encourage them to make an appointment with a GP and perhaps suggest that you go with them. Your GP can do some simple checks to try to find the cause of your symptoms. They can refer you to a memory clinic or another specialist for further tests if needed.

There's no single test for vascular dementia. The tests that are needed to make a diagnosis include: an assessment of symptoms – for example, whether these are typical symptoms of vascular dementia a full medical history, including asking about a history of conditions related to vascular dementia, such as strokes or high blood pressure an assessment of mental abilities – this will usually involve several tasks and questions a brain scan, such as an MRI scan or CT scan , to look for any changes that have happened in your brain Find out more about the tests used to diagnose dementia .

There's currently no cure for vascular dementia and there's no way to reverse any loss of brain cells that happened before the condition was diagnosed. But treatment can sometimes help slow down vascular dementia. Treatment aims to tackle the underlying cause, which may reduce the speed at which brain cells are lost. This will often involve: eating a healthy, balanced diet losing weight if you're overweight stopping smoking getting fit cutting down on alcohol taking medicines, such as those used to treat high blood pressure , lower cholesterol or prevent blood clots Other treatments, including physiotherapy , occupational therapy , dementia activities (such as memory cafes) and psychological therapies , can help reduce the impact of any existing problems.

Vascular dementia will usually get worse over time. This can happen in sudden steps, with periods in between where the symptoms do not change much, but it's difficult to predict when this will happen. Home-based help will usually be needed, and some people will eventually need care in a nursing home . Although treatment can help, vascular dementia can significantly shorten life expectancy. But this is highly variable, and many people live for several years with the condition, or die from some other cause. If you or a loved one has been diagnosed with dementia, remember that you're not alone. The NHS and social services , as well as voluntary organisations, can provide advice and support for you and your family.

Vascular dementia is caused by reduced blood flow to the brain, which damages and eventually kills brain cells. This can happen as a result of: narrowing and blockage of the small blood vessels inside the brain a single stroke , where the blood supply to part of the brain is suddenly cut off lots of "mini strokes" (also called transient ischaemic attacks, or TIAs) that cause tiny but widespread damage to the brain In many cases, these problems are linked to underlying conditions, such as high blood pressure and diabetes , and lifestyle factors, such as smoking and being overweight. Tackling these might reduce your risk of vascular dementia in later life, although it's not yet clear exactly how much your risk of dementia can be reduced.
